Revolt

Lets add some graphics from data logger. I tested Revolt very shortly with data logger installed during the last Finland Cup event in Mänttä.
Batteries used in testing where two 4S Zippy Flightmaxx 2650 mAh in parallel.

The first graph shows battery voltage and current (amps) in Y-axis and time in minutes is shown in X-axis:



To the second graph I selected X-axis to show cumulative mAh used from the battery and power (watts) and battery voltage to be shown on Y-axis:

...and then some pictured results from last night advancements:

World championships were first ever race for Revolt with two new drivers in Autorata Racing
Team: Tino from Finland and Eduardo from Brazil. Already in test track we experienced some
difficulties with broken rear bumper mount and broken body weldings. With tool help from tuunari
we managed to build temporary bumper mount solution and body was fixed with adhesive tape.



"Race was ok, but tracks were slippery" could said in words of Tommi Mäkinen, former Finnish
rally driver and four times rally world champion. Both our drivers were unexperienced in Formula
Offroad. Tino has driven two times in Foff Cup in modified class with his 2WD truck and has
raced in our team competitions in 2WD class. This was however his first ever race with real
Formula Offroad truck. Eduardo has been sponsoring our team by providing the original Revo 3.3
used to build Revolution. Eduardo also owns this Revolt truck modified to brushless and Formula
Offroad by undersigned and PaulJr. This was his first ever driving in gravel pit and with paddle
tires.



There were no problems in truck during the race and despite of my idea to adjust central
differential for the second day, we did not do that as Tino thought there is no need to make
such change. Of course this truck has too short wheelbase for this event and thus it gives
advance for other drivers. Thus only real competitor for our drivers was Daniel with his Summit.
We have to be satisfied as Tino managed to beat Daniel in his first ever race and Daniel has
been racing earlier in last year world championships and in Estonia.

Daniel has drived only one race  WC's 08. Allthough Tino had really good race. He will be contender in next few years

Yes, that's what I understood plus Daniel has driven some races in Estonia according to his web site. May be with different rules, but anyway.

Revolt will make it's second appearance in Formula Offroad race next weekend and this time Tino as the
only driver. Land Rover Defender race body got some damage in last race and this time Revolt will show
up with factory made lexan body. Other changes will be extended wheel base. PaulJr installed new rear
suspension arms which allow either 10 or 19 mm extension to wheelbase. Our selection was the latter
one with total 377 mm wheelbase. Not much compared to any other racer, but this truck is supposed
to be made with low budget.


Extended wheelbase arms on the left vs. stock arms on the right

Wheelbase extension is also another reason for body change as extended wheelbase arms does not fit
with our Land Rover body without cutting wheel arches.

Revolt has not been made for serious Formula Offroad racing nor will we modify it to such purpose. It
serves as good truck for practicing for Tino until new next season race truck called Sörsselsön will be
ready.

This car has just grown out of Unlimited class rules with its second rear axle and six wheel steering. Car will be still easy to convert back to two axis and front wheel steering only, but target is to finalize this build before Christmas holiday season and return the car back to owner.

Driving today on very soft and wet snow ended with drama. Revolt was in super unlimited class setup with six wheel drive using paddle tires. After 1 minute and 50 seconds driving it stopped. ESC was dead. To be exact one phase is dead and thus motor can not operate, while ESC operate otherwise ok. That does not help as it is anyway useless ESC now.

It used 2650 mAh charge during drive (1m 50s) which means 87 A average current. Now wonder that 80 A Hobbywing Ez-run did not last it.
